Once upon a time, a baby Viking, only a few weeks into her time in Valheim, discovered console commands, and said "Screw the bosses! I've got an Epic City to build!!"
A few hundred hours later, after many redesigns, many side tracks, and a whole lot of lag (So. Much. Lag.), Overlook City is done.
This is a full service base build, with a large mead hall inspired by Aegir's Hall in AC Valhalla, A wizard's tower, large farms, a boar pen, docks, portal hub, guest houses, and much more.
Some decorations and plants had to be spawned in with console commands, but otherwise this build is vanilla friendly, although I can't imagine how much material grinding that would take...
